Geth rakudo/Str.no-strands: 4a4c6bb360 | (Elizabeth Mattijsen)++ | src/core.c/Str.pm6
Expose nqp::indexingoptimized as Str.no-strands

Calling .no-strands on a Str will make sure that the string in memory consists of a single array of codepoints, rather than possibly as a collection of strands (which typically happens with a lot of
  ~= work on a string).

[Coke] should no-strands be marked as rakudo-specific? 14:10
or do we want to make it part of the API?
ah, it's a PR. (saw the commit link first. :) will comment there 14:14

[Coke] wonders if that happened because he asked about the opcode recently. :) 14:21

committable6 MasterDuke, gist.github.com/2043f8a66046954ed0...955cc5b24e 19:47
MasterDuke ok, so it's me
AlexDaniel` e: my %s{List}; %s{($_,)} = 1 for (1, "a", 2), (2, "b", 3), (1, "a", 2); say %s 19:49
evalable6 {(1 a 2) => 1, (1 a 2) => 1, (2 b 3) => 1}
AlexDaniel` don't know why ++ doesn't work tho
MasterDuke or the List.new version? 19:50
AlexDaniel` e: my %s{List}; %s{$_,} = 1 for (1, "a", 2), (2, "b", 3), (1, "a", 2); say %s
evalable6 {(1 a 2) => 1, (1 a 2) => 1, (2 b 3) => 1}
AlexDaniel` it's like the single argument rule, except that it isn't x) 19:51
MasterDuke and for the xy problem part of it, i actually want those two (1, "a", 2) to be seen as the same thing 19:52
is there some sort of decont happening that shouldn't? or a binding instead of an assignment?
AlexDaniel` I think it's just parsed horribly 19:53
e: my %s{List}; %s{$_,} += 1 for (1, "a", 2), (2, "b", 3), (1, "a", 2); say %s 19:54
evalable6 {(1 a 2) => 2, (1 a 2) => 2, (2 b 3) => 2}
AlexDaniel` that's pretty close but I really don't know why it's ⇒ 2 for all 19:55
as for treating (1, "a", 2) the same, these are two different lists so I feel like it's not going to work
so basically, you want this: 19:57
m: my %s; %s{.Str}++ for (1, "a", 2), (2, "b", 3), (1, "a", 2); say %s
camelia {1 a 2 => 2, 2 b 3 => 1}
AlexDaniel` but with proper typing. Well…
MasterDuke i've been using .unique(:with(&[eqv])), but it's slow 19:58
AlexDaniel` what's the XY of the XY? Why do you need to count these lists? 20:03
MasterDuke i'm trying to enhance MoarVM/tools/parse_coverage_report.p6 to report the lines that were run that caused a particular line to be covered 20:05
e.g., SETTING::src/core.c/Enumeration.pm6 line 5 was covered by t/spec/S12-enums/basic.rakudo.moar line 3, t/spec/S12-enums/basic.rakudo.moar line 20, t/spec/foo/bar.t line 123 20:07

Make making a Uni between 1.5x and 22x as fast

  - rewrite the slurpy case using nqp: 1.5x as fast
  - add a array[uint32] candidate (native Uni format): 22x as fast
  - add an empty candidate to satisfy tests
The array[uint32] (aka "my uint32 @codepoints") case became a lot ... (16 more lines)
